Overview

Generate high-quality images using a local ComfyUI instance.

✨Key Features

SDXL Default: Uses a high-quality SDXL workflow (Juggernaut XL) by default.

Auto-Backup: Designed to save images to image-gens/ and can be configured to sync to local document folders.

Custom Workflows: Supports external API JSON workflows saved in the workflows/ folder. The script will automatically try to inject your prompt and a random seed into the workflow nodes.

ComfyUI Local Skill

This skill allows OpenClaw to generate images by connecting to a ComfyUI instance running on the local network.

Setup

Server Address: Set the COMFYUI_SERVER_ADDRESS environment variable to your PC's IP and port (e.g., http://192.168.1.119:8189).
API Mode: Ensure "Enable Dev mode" is turned on in your ComfyUI settings to allow API interactions.

Usage

Generate an Image

Run the internal generation script with a prompt:

bash

python3 {skillDir}/scripts/comfy_gen.py "your image prompt" $COMFYUI_SERVER_ADDRESS

Use a Custom Workflow

Place your API JSON workflows in the workflows/ folder, then specify the path:

bash

python3 {skillDir}/scripts/comfy_gen.py "your prompt" $COMFYUI_SERVER_ADDRESS --workflow {skillDir}/workflows/my_workflow.json

Features

SDXL Default: Uses a high-quality SDXL workflow (Juggernaut XL) by default.
Auto-Backup: Designed to save images to image-gens/ and can be configured to sync to local document folders.
Custom Workflows: Supports external API JSON workflows saved in the workflows/ folder. The script will automatically try to inject your prompt and a random seed into the workflow nodes.

Implementation Details

The skill uses a Python helper (scripts/comfy_gen.py) to handle the WebSocket/HTTP handshake with the ComfyUI API, queue the prompt, and download the resulting image.

ComfyUI Image Generation Notes:

Server Address:
The ComfyUI server address needs to be passed as a direct argument to the comfy_gen.py script after the prompt, not just as an environment variable.
Example: python3 ... "Your prompt" http://192.168.1.119:8189 ...
Workflow Paths:
When specifying a workflow file path that contains spaces or special characters, it must be enclosed in single quotes to be parsed correctly by the script.
Example: --workflow '/path/to/your/workflow file name.json'
Lora Weight Control:
The current comfy_gen.py script does not appear to have a direct parameter for controlling Lora weights (e.g., setting 'l1lly' Lora to 0.90). This might need to be configured within the workflow JSON itself, or require modifications to the script or workflow.
Output Filenames:
Generated images might be saved with temporary names (e.g., ComfyUI_temp_...png) rather than more descriptive ones by default.
ComfyUI Setup:
Ensure "Enable Dev mode" is turned on in ComfyUI settings for API interactions.
